Hi, My cars been in a few times for the traction control light coming on and staying on for the rest of the day, but they don't seem to be able to find anything and say no errors come up on the computer. It seems to come on if im going down a hill in traffic at say 10mph in second using engine braking. When it does this it will sometimes stay on all day or will go out after a few times the ignition has been off. It also flickers when you go over a bump at speed, like a few flashes. Has only done this on a bump on the l/h/s although i guess there are more pothioles on the left of the road. Have tried to see if the traction control works when the light is on but i cant really decided as traction is too good. Its getting close to the end of its warrenty so i could do with it being rectified. Any ideas? Its a 3.2 Quattro... Cheers p.s the light wont go off when i press the button.
